Null error Thread

[anoorally]

Hi, I have this thread code which was running fine a few hours ago but now it gives an error "null" as description. I didn't change any codes relating to threads:

    public class constantReading implements Runnable {
        
        public void run() {
            try {
                //System.out.println("reading thread started");
                
                while (true) {
                    Object obj = Objectin.readObject();
                    filterData(obj);
                }
            } catch (Exception e) {
                print("Error in reading thread: " + e.getMessage());
            }
        }
    }

And this is the output:
Error in reading thread: null

Any idea whats wrong?

A full stack trace will let you track down the code that is throwing the cryptic exception.

} catch(Exception e) {
    e.printStackTrace();
    print("Error in reading thread: " + e.getMessage());
}

Thank you for your quick reply :) I got the error source.
